“…Congestion in power system is a situation in which the transmission system is not able to fulfill all the desired transactions due to power system's physical and operational limitations [37]. These physical and operational limitations can be thermal limits of transmission lines and transformer, voltage limitations, and transient or other stability limits [38].…”

“…Congestion management is the process of making use of available power system infrastructure (economical and operational) while operating within system constraints [41]. Congestion management gives long-term investment signals to the TSO for strengthening local (to a single TSO) or cross-zonal (shared with other TSOs) transmission system infrastructure.…”

“…A TSO responsible for a given control area or multiple TSOs responsible for the concerned control area must compensate the cost for remedial actions for congestion management [15]. A number of methods have been proposed for congestion management in [38][39][40][41][42][43], these can be broadly categorized into two methods i.e., technical and non-technical methods. Technical methods of congestion management can be cost free and not cost free [44].…”

Liberalization of electricity markets has brought focus on the optimal use of generation and transmission infrastructure. In such a scenario, where the power transmission systems are being operated closer to their critical limits, Ancillary Services (AS) play an important role in ensuring secure and cost-effective operation of power systems. Emerging converter-based HVDC technologies and integration of renewable energy sources (RES) have changed the power system dynamics which are based on classical power plant operation and synchronous generator dynamics. Transmission system interconnections between different countries and integrated energy markets in Europe have led to a reduction in the use of energy from non-renewable fossil-based sources. This review paper gives an insight into ancillary services definitions and market practices for procurement and activation of these ancillary services in different control areas within the European Network of Transmission System Operators for Electricity (ENTSO-E). The focus lies particularly on ancillary services from HVDC systems. It is foreseen that DC elements will play an important role in the control and management of the future power system and in particular through ancillary services provision. Keeping this in view, the capability of HVDC systems to provide ancillary services is presented.

“…There several methods adopted for congestion management in power system such as Generator Rescheduling (GR) method, Distribution Generation (DG) method, cost free methods, nodal pricing methods, and load shedding methods. The reviews of the methods are shown in [7]. Author in [8] presented a novel technique for congestion management in 5-bus network by controlling the active power flow using TCSC and author considered sensitive analysis for location of TCSC device.…”

This paper proposes a new FACTS device, i.e., Unified Power Flow Controller (UPFC) to relieve power congestion on power grid network. A simple model of a three phase AC–network of 500/230kV, 5-bus network with two transformers and two power generation plants (1000MW, 500MW) is designed. UPFC is designed with IGBT converters connected in shunt- series and both interconnected with DC bus and connected to AC side with transformer and coupling reactors. A contingency case is considered such that two transformers are considered instead of three transformers. The power flow of an UPFC installed at Bus-3 in 5-bus system is analyzed to show how the congestion of power on the grid is relieved through it. A bypass circuit breaker is installed at Bus -3 in the circuit to show the natural power flow without UPFC and power flow after installation of UPFC. The topology of series converter build in UPFC can introduce maximum of 10% of line-ground voltage in series. The simulation network of the 5-bus transmission network with UPFC connected at Bus-3 is designed with MATLAB/SIMULATION Software to estimate the power flow with UPFC connected.

“…In deregulated power market congestion management is very complex task for system operator when compared to regulated system [2]. The literatures [3][4] have explained different methods and techniques of congestion management. Different problems due to congestion and congestion management by FACTS devices are explained in [5].…”
